  • Method for hydrocarbon recovery from an underground formation by injection of a saline aqueous solution comprising a surfactant
    Patent number: 11578573
    Abstract: The invention relates to a method for recovery of hydrocarbons present in an underground formation by injection of a saline aqueous solution comprising at least one surfactant, by means of a numerical flow simulator including a model of the evolution of the interfacial tension between the saline aqueous solution and the hydrocarbons as a function at least of salinity, wherein the interfacial tension evolution model is calibrated as follows: i) carrying out interfacial tension measurements for a plurality of emulsions having distinct salinity values corresponding at least to the optimum salinity, to two salinities bounding the optimum salinity in a 5-10% limit, to the zero salinity and to the solubility limit of the salts; ii) determining the constants of the interfacial tension evolution model by minimizing a difference between the model and the interfacial tension measurements.

  • Process for the exploitation of a deposit of hydrocarbons by injection of a polymer
    Patent number: 11136863
    Abstract: A process for the exploitation of a deposit of hydrocarbons by injection of an aqueous solution with polymer includes calibration of the constants involved in an analytical expression of a model for displacement of the polymer which is a function of at least the concentration and of another parameter, such as the salinity, the shear rate and the temperature.
